Metastatic tumors tend to have a rapid course, and evidence of neoplasia elsewhere usually can be obtained. Multiple upper and lower cranial nerve palsies usually evolve. Glioma from the brainstem or cerebellum also can invade the cerebellopontine angle, producing symptoms of a cerebellopontine angle mass lesion. Aneurysms also may appear in the cerebellopontine angle.
